Beat the cream cheese until it is light and airy.
Add in the eggs, one at a time, then the vanilla and sour cream. Mixing well after each addition. This is where you get the "lightness" so take your time.
Beat in the sugar, cinnamon and cornstarch until well mixed.
Gently fold in the apples and caramel.
Once the apples are evenly distributed the batter is ready for the pan.
